1. PYNPUNT GEDREWE OPENING

Are your coke screening operations plagued by persistent, duur ondoeltreffendheid? Plant managers and engineering contractors face significant challenges in maintaining consistent product quality and throughput. Algemene pynpunte sluit in:
Verblinding & Oordrag: Moisture and fine particles adhere to screen decks, blinding apertures and forcing material carryover. Dit lei tot 'n afsonderlike produk, verhoogde herverpletterende vragte, and wasted yield.
Oormatige stilstand & Onderhoud: Frequent screen cloth changes and structural repairs due to aggressive vibration or material abrasion halt your production line, 'n direkte impak op jou winspunt.
Inkonsekwente grootte & Opbrengsverlies: Ineffective screening leads to missized coke fractions, compromising blast furnace efficiency for your customers and eroding your profit margins.
Hoë bedryfskoste: Voortydige komponent mislukking, hoë energieverbruik van ondoeltreffende aandrywers, and laborintensive cleaning procedures inflate your costperton.

Is there a screening solution engineered to withstand the abrasive nature of metallurgical coke while delivering precise separation with maximum uptime?

2. PRODUK OORSIG

The ISOCertified Coke Vibration Screen is a heavyduty linear or elliptical motion vibrating screen specifically engineered for the dry separation of metallurgical coke into precise size fractions (bv., hoogoond coke, neut coke, briesie). Its robust design addresses the unique abrasiveness, digtheid, and size range of coke particles.

Operasionele werkvloei:
1. Voer & Verspreiding: Sized coke from crushers is evenly distributed across the full width of the screen’s feed box.
2. Stratifikasie & Skeiding: HighGforce vibration stratifies material; fines pass through the configured screen cloth apertures while oversize travels toward the discharge end.
3. Ontslag: Correctly sized fractions are discharged into separate chutes or conveyors for stockpiling or shipment.

Toepassingsomvang: Primary and secondary screening of metallurgical coke in coke plants, staalfabrieke, en grootmaat hantering terminale. Ideal for sizing ranges from 80mm down to 05mm breeze.

Beperkings: Not designed for wet screening applications or for materials with extreme temperature (>150°C) without specific modifications.
